I have a logo placed in the Player for all our Storyline projects. I output to .zip as a SCORM file for LMS. In our case, we use both Blackboard and Moodle. When I look at the playback, all works fine on my computer. If I go to a guest computer, and look at the same lesson, the logo is a broken image. Even if I'm signed in as an admin for Moodle, or as a teacher on Blackboard.
